Cyanoacrylate Use
Aug 02, 2018

Cyanoacrylate is a resin that is acrolein-based. When super-adhesive is applied to the surface of an object, the solvent evaporates, and the surface of the object or the moisture from the air (more precisely, the hydroxide ions formed by moisture) The monomer is rapidly anionized to form a long, strong chain that bonds the two surfaces together. Since the polymerization process is an exothermic reaction, it can be found that the temperature rises slightly, and since the solvent (acetone) evaporates therebetween, the use of the super-glue can smell some unpleasant odor.

Since moisture can polymerize cyanoacrylate, long-term exposure of a super-adhesive to air can cause it to be used again. To prevent this from happening, we can store the opened super-adhesive in an airtight Bottle and put the gelatin in the bottle.
